✦ Synopsis

A target screen stimulus takes into account the necessity of larger checkerboard patterns with rising eccentricity. The target pattern should be calculated to fit the retinocortical magnification factor. This proposition is based on the working hypothesis that for maximal visual evoked potential (VEP) amplitude the stimulus should appear on the cortex as an undistorted checkerboard pattern. We describe the cortical response elicited by four different target screen stimuli based on a similar algorithm. No significant difference to normal checkerboard was found.

Visually evoked potentials on pattern stimulation are lowered by cataracts via scatter, absorption and defocusing. These effects have to be known before pattern stimulation can be fruitfully applied in patients when a lowered vision cannot or can hardly be explained by the cataract. It was remarkabl

Pattern-reversal visual evoked potentials (PR-VEPs) and EEG were recorded in 14 phenylketonuric (PKU) children on a low-phenylalanine (phe) diet; the data obtained were correlated with metabolic parameters, namely, the actual phe plasma level, the mean phe plasma level in the last year, an the begin
